2 Claims.

This invention relates to new and useful im provements in an automatic cocktail shaker.

The invention has for an object the construction of a cocktail shaker which is characterized by the fact that it is composed of a standard with track elements, a receptacle holder adapted to be slidably mounted on the track elements and connected with a reciprocating mechanism mounted on said standard.

It is proposed to so construct the device that the receptacle holder is capable of receiving and holding a glass or similar container.

As a further object of this invention it is pro posed to provide a novel mechanism for holding the receptacle in position.

Still further the invention contemplates to provide a construction which permits two glasses set with their open ends one within the other to be mounted upon the receptacle holder and shaken.

Still further the invention proposes a novel arrangement for holding the glasses in position on the receptacle holder. It is proposed to characterize the holding mechanism by the fact that the parts pass a certain dead center and so lock themselves in position in the holding condition.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:-

Fig. 11 is a fragmentary side elevational view of Fig. 9.

Fig. 12 is a fragmentary elevational view of a clamp portion, this view being shown as though looking in the direction of the line I2|2 of Fig. 11.

The automatic cocktail shaker, according to this invention, comprises a standard Ill having track elements Ii mounted thereon; A receptacle holder i2 is adapted to slidably engage the track elements and is connected with a reciprocating mechanism consisting of an electric motor l3 attached on the standard ID, a crank element l4 driven by the motor, and a rod I5 connected between the crank element and the receptacle. l

The standard ll comprises a base portion Ill upon with a bracket Ill is secured. This bracket is formed with an opening 16 extending from the bottom slightly above the center. The track elements I I are secured along the sides of this opening. The receptacle holder comprises an arm element l! to one side of which there is secured a Complementary track element l8. 1 This complementary track element engages the tracks I I as clearly shown in Fig. 6. The parts are thus slidably connected together.

A stud l9 projects from the arm ll. The rod I5 is secured at its upper end pivotally upon the stud. A base cup 20 is secured upon the arm l8 0 and is adapted to receive a glass or other receptacle, indicated by the dot and dash lines 2|. A bar 22 is pivotally mounted upon the top of the arm I! by a pintle 23. This bar supports a top cup 26 adapted to engage over the top of the, receptacle 2|. A mechanism is provided for releasibly clamping the arm 24 in a lowered po sition.

The mechanism mentioned in the previous paragraph consists of a handle 25 pivotally mounted by a pintle 26 in an off-set position on the arm 22. A rod 21 extends through the arm 22 and against a portion of the handle 25 andis arranged so that when the handle is moved upwards the rod is forced inwards. The end of the rod projects from the arm 25 and engages a bridge element 28 whch extends transversely, and engages against the upper end of a pair of springs 29 which are secured at their lower ends by screws 30 on the arm IT. A lever 3! is pivotally mounted by a pin 32 at its bottom end on a post 33 attached on the arm IT. This lever 3| extends upwards and is fixedly connected with the bridge 28 which freely rests against the rod 21.

Intermediate of the lever 3| there is a latch element 34 which is pivotally connected therewith by a pin 35. This latch element extends through a small opening in the arm I! and its front end is adapted to engage a knob 36 formed in a rod 31. This rod is slidably mounted through a bracket 38 attached on the arm IT. The lower end of the rod 31 is provided with a top element 39. The upper end is pivotally connected by a pin 40 with the arm 22.

In Fig. 4 the receptacle holder is shown in the act of holding the receptacle 2|. In this condition the receptacle holder is connected with the reciprocating mechanism and the drink contained in the receptacle may be mixed. To remove the receptacle it is merely necessary that the handle be moved upwards so that it presses in the rod 21 which forces back the lever 3|, which in turn draws the latch element 34 rearwards and frees the rod 31. The arm 22 is now free to be lifted upwards as indicated by the dot and dash lines. Then the receptacle 2| may be removed.

In Figs. 9 and 10 a modified form of the invention has been disclosed which is characterized by thefact that the receptacle holder is capable of holding a pair of receptacles 2| and 2| having their open ends inter-engaged with each other. The receptacle 2| is rested on the cup 20' which is secured on the arm IT. This arm I1 is provided with a track element I8 to which the screw I9" is connected. At the upper end of the arm I? therev is a cup element 24' which is connected with an arm of bell shape.

A-pintle 46 pivotally connects the arm 45 at its center upon the arm IT. The other end 45 of the arm 45 extends downwards and is provided with a pin 48 which engages in a slot 49 formed in the vertical arm of an L-shaped lever 50. This L-shaped lever is pivotally mounted by a pin 5| intermediate of its ends. The other end of the L- shaped lever is provided with a pin 52 engaging a slot 53 in an arm 54 which is pivotally supported by a pin 55 upon a bracket 51. The arm 54 conmeets with a'gripping element 58 adapted to encircle the upper portion of the receptacle 2| A stop element 59 is formed on the arm I! and has a front face of resilient material such as soft sheet rubber.

In Fig. 9 the receptacle holder is shown in its operative position holding the receptacles 2 l and 2| in position. In this condition of the device the pin-48 is past its dead center against the bottom of the slot 49 so that the parts are locked. The ends 45 of the arm 45 and the end of the lever 50 engage against the resilient material 60 which acts as a stop to prevent the parts from moving too far past the dead center.

The receptacles may be removed by manually forcing the cup 24' upwards to the dot and dash position. This automatically forces the pin 48 against the bottom of the slot 49 past the dead center and then the bell crank pivots clockwise. The holding element 58 pivots to a raised position sis-indicated by the dot and dash lines. The receptacles are now free to be removed. The receptacles may be again held in position by merely forcing the cup element 24 back to its original position.

In Figs. 11 and 12 another modified form of the invention has been disclosed which distinguishes in several respects from the form of the invention shownin Figs. 9 and 10. According to this form of the invention there is an arm Il from the upper end of which there is supported a top cup 24" connected with an arm 45" pivotally mounted by a pin 46 on the arm Il The arm 45 is provided with an extended portion 45 carrying a pin 48" engaging in a slot 49" of a bell shaped lever consisting of the arm 50" pivotally supported by a pin 5|" and having an extended end 5|) which supports a clamp element 58". The clamp element 58 is formed with an open side 58 (see Fig. 12) so that the receptacle 2W may be forced-from its grip. I

In Fig. 11 the cup 24 is shown holding the receptacle 2| a in position. To release the receptacle it is necessary that the cup 24" be moved upwards to the dot and dash position. This immediately pivots the pin 48" from its dead center position anti-clockwise and pivots the bell crank 50" clockwise. This moves the clamp 58" downwards to grip the receptacle 2| Thus the receptacles are held from accidental spilling. The receptacle 2| may easily be forced from the glass 58".

While I have illustrated'and described the preferred'embodiments of my invention, it is to be understood that I do not limit myself to the pre- Y else constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
